Appendix A Replacing Memory Components
Replacing Flash Memory SIMMs
Caution
It is critical that the correct Flash memory SIMM modules be installed in the Cisco AS5400
and Cisco AS5400HPX universal gateways. The Cisco AS5400 only supports 5V Flash
memory SIMM modules and the Cisco AS5400HPX only supports 3.3V Flash memory. In
addition, system flash and boot flash modules for the Cisco AS5400 are not
interchangeable with those for the Cisco AS5400HPX. Using the incorrect memory will
cause the system to malfunction and may cause damage to the system board or memory
card.
Tips
To help identify your universal gateway, starting with Cisco IOS Release 12.2(11)T, the
show version
and
show diag
commands will identify the universal gateway as an
AS5400
or
AS5400HPX.
Prior to this release, these commands showed the universal gateway as an
AS5400
, even if it was a
AS5400HPX.
Note
Flash memory should be reformatted after adding, replacing, or removing flash
memory SIMMS.
•
One socket holds a SIMM for the boot helper image (rxboot) software. This SIMM, labeled SIMM,
must also be installed. The SIMM can be 8, or 16 MB.
The Flash memory SIMMs must be purchased from Cisco. For ordering information, refer to the
“Obtaining Technical Assistance”
in the Preface.
